AUXILIARY HEATING DEVICE.

Application filed January 14,1929. Serial No. 332,426.

The invention is particularly devised for selective restriction of flow of gases from a furnace into one or another of a plurality of conduits, for example for flow through an auxiliary heater or directly to the chimney. The hot gases tend to cause expansion of the valve members, whereby the operation of the valve may be impeded or prevented. A further object of the invention therefore is to provide a valve that willoperate etlicient-ly irrespective of effects of heat thereon.

A housing fora valve for controlling the flow of gases must usually be positioned at the smoke outlet of the furnace, the location of an auxiliary heater is determined by factors such as the position of the chimney inlet which are not under the control of the person providing the installation, and crowded conditions in a basement may render it diilicult or impossible, to relate the valve housing properly to the furnace and auxil- :iary heater for most etficient operation of I the installation.

be promo ted.

Further objects of my invention therefore are to provide a valve and valve housing that may be ad usted to the relatively fixed positions of the furnace chimne and auxiliar heater for proper and easily efl'ectcd control of the flow of gases, and whereby the mosteiiicientoperation of the installation may Fig. 3 is a detail perspective view of the alve-supporting bolt and plate.

Referring in detail to the drawings:

1 designates a furnace having a short smoke outlet flange 2, 3 a chimney, 4 an auxiliary heater box, 5 a direct conduit for direct flow of gases from the furnace to the chimney, 6 an outlet pipe from the auxiliary heater toward the chimney connected to the direct conduit at 7, and 8 a by-passing pipe for conducting gases from the furnace into the auxiliary heater.

he auxiliary heater may be of any preferred construction, for example such as the heater disclosed inmy co-pending application, Serial No. 288,421, to which the invention presently described is particularly adapted, the pipe 8 extending angularly and having an elbow 9 connected into the end wall 10 of the heater adjacent its lower end, and an elbow 11 adapted for connection into the device presently described for controlling the flow of products of combustion.

My present invention includes a housing 12 comprising preferably a metal box including side walls 13 and 1 1 having centrally located openings 15, and end walls 16 and 17 having similar centrally located openings 18, and a top or cover 19 having a longitudinal slot 20 for a purpose later described. The axes of the openings 15 and 18 are preferably in the same plane. The lower edges of the walls 13, 14 and 17 are provided with slide-supporting flanges 21 and ribs 22 forming grooves 23 and the end wall 16 is shortened for admitting to the grooves a sliding plate 24 forming the bottom of the housing and which may be removed for access to the inside of the housing for cleaning the same and for other purposes presently disclosed.

At each opening 15 and 18 is an annular flange 25 projecting outwardly from the housing to receive the furnace outlet flange 2, the direct conduit 5, the elbow 11 of the by-passing conduit, or a cap 26 for sealing an opening in which no pipe is positioned, whereby gases from the furnace will be conducted intothe housing for controlled flow into the auxiliary heater or directly to the chimney. i

In the illustrated use of the invention, the auxiliary heater pipe 8 is connected'to the housing at the opening in the side wall 14, in alignment with the furnace outlet flange 2 to the flange of the side co aluit is connected to over the posite to communicates.

S. ably mounted on the cover 19 closing the slot is a plate 2'! and a stem or M 7 L 1 boil 2S secuieo to the plate entends the slot and is freely inova *le the a ll" valve 29 I into and out oi engagee end wall 1'? to obstruct and i .w o gzues through the direct flow conduit 5, l tally control the flow w :,-i u, e aunihaiy neatei, since die L 13 l to n the v housing-supported sli ing pl by a nead 83 which may be a nut, nut threaded on the bolt is couute n 9 re cess of the plateso thati i may de over J. L the cover and attach the plate the bolt withrelative rigidity.

Spaced guide rails 36 are furtier inounted on the cover to retain the olate 2, in a rectilinear path, and assure closing of the slot by the plate.

The ends of the slot 20 are equally spaced from the opposite end edges of the cover, whereby the valve may be reversed and may be moved into engagenientwith' the opening in the end wall 15 to close the same.

A chain 3'? may be secured to the upper end 38 of the bol and passe-a over pulleys and 40 mounted on lrachets ll and secured to the housing, and aligned with the bolt, and passed over pulleys such as and supported from of the basement, to provide aloop l6 conveniently located, for exar ple at the furnace door, for operating the valve.

lVhen a plurality of conduits are to be installed for passage of gases from a furnace to the chimney, for example when an auxiliary heater is provided, the auxiliary heatniay be mounted in any desired relation to the furnace. The valve housing may then be mounted on the outlet flange of the furnace with the pipe engagino' the annular llan 'e in one of the side walls of the hous ing, for flow of gases frointhe furnace to the housing; an elbow may be mounted on the flange of the opposite side wall for connecting the housinq' to the auxiliary heater, the direct flew conduit may be connected to 1 the bolt so either one of the end walls, and a cap may be installed on the opposite end wall to close the housing.

The direct flow con ed or accessib" .E'; on The valve may be rotated on that its face is presented to the end wall with which the direct outl pipe is connectec, and the sliding pla e may then be moved by means of the chain into and out of the prefer the condui'.

The valve may be mounted in the housing after the latter is connected to the several pipes, the sliding bottom being withdrawn for access to the housing, the bolt bein inserted through the slot and the disk valve adjusted thereon.

The vertical walls of the housing may be short, because of the character of the valve controlling thefflow of gases, and the means for operating it, and contrasting for exampie with a housing having vertically aligned openings in one wall to receive the directilow conduit and the pipe leading to the auxiliary heater.

The supporting plate slidable over the cover of the valve housing closes the slot and is easily operable through the chain.

The slot is substantially wider than the diameter of the valve-supporting bolt, so that expansion of the parts due to heat of gases oassing from the furnace will not cause the conduits, and means including a bolt slidable in the slot for moving the valve.

2. In combination with a furnace having an outlet for products of combustion, a plurality of conduits, a slotted housing connected to the outlet and the. conduits, a stem extending through the slot of the housing and sliuable therein, and a disk adjust-- abl mounted on the stern within the housing and movable into closing relation with one of the conduits.

8. In combination with a furnace having an outlet for products of combustion, an auxiliary heater, and a chimney, avalve housing including similar side and end walls having similar openings, i'neans connecting the outlet with one of said walls for flow of products of combustion from the furnace into the housing, a pipe mounted in the opening of another of said walls and connecting the housing with the auxiliary heater, a conduit mounted in the opening of another of said walls and connected to the chimney, and means movable in the housing for controlling flow of products of combustion from the housing into said conduit.

at. A device of the character described for controlling flow of fluids into a plurality of conduits, comprising in combination with conduits, a housing including walls having outlets into said conduits, a valve bodily movable in the housing into engagement with one of said walls to close the outlet therein, the housing including a wall having a slot parallel to the axis of said valved outlet, and a stem on the valve slidable in the slot for operating the valve.

5. In a device of the character described for controlling flow of gases trom a furnace outlet pipe, in combination with an outlet pipe and a plurality o'l conduits, a housing comprising opposite side walls having registering openings, the outlet pipe and one of said conduits being connected to saidside walls in alignment at said openings, the housing having end walls provided with registering openings for selective mounting a valve movable in the housing for controlling the flow oft gases through said selected end wall into said other conduit, the housing having a cover provided with a slot, a plate slidable on the cover and closing the slot, and a stem secured to the plate and extending through the slot for supporting the valve, and movable longitudinally of the slot for operating the valve.

6. In a device of the character described for controlling flow of gases from a furnace to a chimney, a housing having an inlet from the furnace, a direct flow outlet toward the chimney, and a by-passing flow outlet, a

cover for the housing having an elongated slot parallel to the axis out the direct flow outlet, a threaded stem extending in the slot, a valve adjustably mounted on the stem and bodily movable toward and away from the direct flow outlet, and means for supporting the valve including a plate connected to the stem and slidable on the cover, said plate being adapted to close the slot.
